What version of Solr are you using? ‘cause 8x has this definition for _version_
<!-- doc values are enabled by default for primitive types such as long so we don't index the version field --> <field name="_version_" type="plong" indexed="false" stored="false"/> and I find no text like you’re seeing in any schema file in 8x…. So with a prior version, “try it and see”? See: https://issues.apache.org/jira/browse/SOLR-9449 and linked JIRAs, the _version_ can be indexed=“false” since 6.3 at least if it’s docValues=“true". It’s not clear to me that it needed to be indexed=“true” even before that, but no guarantees. updateLog will be defined in solrconfig.xml, but unless you’re on a very old version of Solr it doesn’t matter ‘cause you don’t need to have indexed=“true”. Updatelog is not necessary if you’re not running SolrCloud... I strongly urge you to completely remove all your indexes (perhaps create a new collection) and re-index from scratch if you change the definition. You might be able to get away with deleting all the docs then re-indexing, but just re-indexing all the docs without starting fresh can have “interesting” results.
